Affectionately dubbed The Red Hot Cam, they have put this camshaft in a wide variety of LS3 engine combos, and it was spicy enough to make excellent power in both boosted and N/A applications! Things really heated up once it was installed and running on the engine dyno. It showed excellent power gains over the existing Stage 2 PDS and LS3 Centrifugal cam profiles even with less intake duration. Using BTR lobes designed in house, this cam had just the right amount of kick that combined both great stability and durability during Spintron testing. Scoring a 1.5m SHU (Think Carolina Reaper and Pepper Spray) on the Scoville Scale, this cam is sure to add some heat to your LS3 build! If installing in an engine originally equipped with a 1-bolt camshaft, a 3 bolt conversion kit will be required.
